| 40px | This is a documentation subpage for Template:Infobox globular cluster. It contains usage information, categories and other content that is not part of the original template page. |
Infobox for articles on globular clusters.
Usage
Fields should generally be directly from the source, such as SIMBAD. Wikilinks and expansion of abbreviations are acceptable.
Example infobox
The following parameters can be used to create a globular cluster infobox. Please remove any parameters that are not likely to be useful.

Parameter documentation
| Field | Description |
|---|---|
| name | Common name of the globular cluster. This field is required. |
| image | Photograph of the cluster. Preferably this should be a wide shot to show most/all of the globular cluster rather than a view from within it. Include the "File:" prefix and a width of 300px. If uploading a new image, please put them on Commons so they can be easily used by the other language Wikipedias. |
| caption | Description of the photograph in the image field. |
| credit | Credit for the photograph in the image field. |
| epoch | The astronomical epoch of the cluster coordinates (below). Normally this is [[J2000]]. |
| class | The Shapley–Sawyer Concentration Class of the cluster. |
| constellation | A link to the constellation where this cluster is located. |
| ra | The right ascension coordinate of the cluster mid-point. The {{RA}} template should be used here. For example: {{RA|16|17|02.51}}. |
| dec | The declination coordinate of the cluster mid-point. The {{DEC}} template should be used here. For example: {{DEC|–22|58|30.4}}. |
| dist_ly | This is an estimate of the cluster's distance from the Solar System in light years. |
| dist_pc | This should be the same distance as dist_ly using parsec as the units. A parsec is equal to 3.2616 light years. |
| appmag_v | The apparent magnitude of the cluster. |
| size_v | This gives the angular diameter, usually in arc minutes or arc seconds. |
| mass_msol | The estimated total mass in solar masses. |
| mass_kg | The same value as above, using kilograms as units. A solar mass is equal to 2 × 1030 kg |
| v_hb | The visual magnitude of the horizontal branch stars in the cluster |
| age | The estimated age of the cluster, usually listed in [[Gigayear|Gyr]] (billions of years). |
| notes | Additional details of significance. |
| names | A comma separated list of used alternative cluster names. These are names that are commonly used in scholarly journal articles, such as the New General Catalogue (NGC) name. |
